Bob -
The Pegasus does not switch the power supply. The power supply is on at
all times. The ON/OFF switch on the front of the Pegasus is a two wire
connector labeled "1" that goes to the DC input board that holds the relay.
I tried the Pegasus with two different power supplies, one switcher and
one linear. It does not work on them, but does work off a battery. I'm
confused.
Thanks for the suggestion.
